Olight 21700 3,6V 5000mAh Battery

The 5000 mAh battery in 21700 format works perfectly. It provides long flashlight runtime and is very reliable. The built-in protection (PCB) is a key safety feature. I definitely recommend it.

I got the battery with the torch, but it doesn't last long. The price is completely inadequate for the quality and the manufacturer's assurances. I do not recommend this product.

Great battery, lasts a long time – I've been using it for over a year in my Olight headlamp and I recommend it. It would be great if external chargers were made for them.

I bought this battery as a spare for the Olight Seeker 4 Pro. Surprisingly high capacity for such a small and light cell. Very well made, with overcharge and deep discharge protection. Looks like a premium product. I recommend it.

I use the battery in my Seeker 4 Pro torch – one came in the set, the other was bought separately. Despite frequent use, I haven't yet managed to discharge them completely.

Very good battery. I use it in the Olight Warrior X Turbo torch. At maximum power it works perfectly. I have 4 of these batteries and not a single one has let me down yet.

I use it in the Olight Warrior 3 tactical torch. The battery holds energy for a long time and comes packed in a practical plastic box for two pieces.

I bought two batteries for the Olight Perun 2 and M2R Warrior. They work perfectly, retain energy for a long time. I practically didn't notice them discharging without use. I always have the M2R Warrior with me and it works for months without needing to be charged. I use the Perun 2 for night walks with my dog and it also needs charging very rarely, maybe once a month.

Everything is fine, solid battery: heavy, compact and capacious, charges quickly and fits the torch. Holds energy for a long time, definitely recommended as a replacement. The package arrived very quickly.

I chose this battery as a spare because it’s not standard and hard to find in stores. It lasts a long time, overall I’m satisfied. The purchase process was smooth and very quick.

I bought an extra cell as a spare for the Seeker 2, and I also intend to use it as a replacement in the Perun 2 – recommended from my side. Shipping as always was lightning-fast.

I bought it as a spare for the Warrior X Turbo. I appreciate that militaria.pl included a plastic box – thanks to this, the battery doesn't move around loosely in the backpack. I recommend it. And the Warrior itself for patrols too :D

Great battery – the very high capacity means the Baton 3 Pro Max works for a really long time. It's good to have a spare, especially for longer treks. There are times when maximum mode is needed, which drains the battery quickly.

This is really a great battery – its large capacity means the Baton 3 Pro Max lasts a very long time on it. For longer trips to the forest, it's worth having a spare. Sometimes the highest mode is needed for a longer time, then the battery drains faster.

Perfect as a spare battery for the Perun 2 torch, has a high capacity.
